[0052] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0053] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0054] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.

[0055] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present.

[0058] Figure 1 1 is a schematic structural diagram of a light box 100 according to an embodiment of the present disclosure. Figure 2 1 is a schematic cross-sectional view of a partial structure of a light box 100 according to an embodiment of the present disclosure.

[0059] like Figure 1 and Figure 2 As shown, the light box 100 of the present disclosure may include components such as a back panel 110, a light-emitting component 120, a panel 130 and a side portion 140. When in use, the light box 100 of the present disclosure can be hung on a wall that is approximately vertically arranged. Accordingly, the back panel 110 and the panel 130 will be arranged approximately vertically, and the side portion 140 will be arranged approximately horizontally. Moreover, the surface of the light box 100 close to the wall is its rear surface, and conversely, the surface away from the wall is the front surface of the light box 100. In addition, the portion between the front surface and the rear surface is the outer peripheral surface of the light box 100.

[0060] Figure 3 It is a schematic structural diagram of a backplane according to one embodiment of the present disclosure.

[0061] like Figure 3 As shown, the back plate 110 is formed in a plate shape and is formed into a substantially quadrilateral structure. Of course, the back plate 110 of the present disclosure can also be set to other shapes according to different installation environments, and the present disclosure is not limited to this.

[0062] The back plate 110 is preferably made of aluminum-plastic plate. Of course, it can also be made of thermally conductive material, so that the heat generated by the light-emitting component 120 can be dissipated through the back plate 110 and the temperature inside the light box 100 is kept within a reasonable range, preventing the light box 100 from being damaged due to high temperature and other problems.

[0063] Heat dissipation holes 111 may be provided on the back panel 110, whereby gas can enter the interior of the light box 100 through the heat dissipation holes 111 located below and be discharged through the heat dissipation holes 111 located above, thereby forming a gas flow path inside the light box 100 and cooling the heat-generating components in the light box 100 (such as the light-emitting component 120 and the transformer, etc.) through the flowing gas, thereby preventing the temperature inside the light box 100 from being too high.

[0064] More preferably, the heat dissipation holes 111 can be formed as elongated holes, with the length direction of these elongated holes arranged horizontally (for example, when the back plate 110 is arranged vertically), and multiple heat dissipation holes 111 can be formed into a heat dissipation hole group. For example, every three heat dissipation holes 111 can form a heat dissipation hole group. Accordingly, the back plate 110 can be provided with four heat dissipation hole groups, which are arranged in two rows and two columns.

[0065] Refer again Figure 3 The back panel 110 of the present disclosure is provided with a mounting hole 112, so that the light box 100 of the present disclosure can be hung on a wall through the mounting hole 112. For example, when the light box 100 of the present disclosure is in use, a screw can be installed on the wall, and the head of the screw can pass through the mounting hole 112 and be located inside the light box 100. The screw cooperates with the hole wall of the mounting hole 112, so that the back panel 110 is supported by the screw.

[0066] Specifically, the mounting hole 112 has a circular hole portion and an elongated hole portion connected to the circular hole portion; wherein the elongated hole portion is vertically arranged, and the center line of the elongated hole portion passes through the diameter line arranged in the vertical direction of the circular hole portion. Moreover, the width of the elongated hole portion is smaller than the diameter of the circular hole portion. Accordingly, the diameter of the head of the screw is smaller than the diameter of the circular hole portion and larger than the width of the elongated hole portion. Moreover, the size of the shank of the screw is slightly smaller than the width of the elongated hole portion, so that when the light box 100 of the present disclosure is held by the screw, the shank of the screw can be located in the elongated hole portion. Therefore, after installation, the light box 100 of the present disclosure can be firmly held on the wall and is not prone to shaking.

[0067] In the present disclosure, there are four mounting holes 112, which are respectively located at the four corners of the back plate 110. Moreover, taking the back plate 110 as an example of being vertically arranged, the elongated hole portion of the mounting hole 112 is located above the circular hole portion.

[0068] like Figure 3 As shown, the back plate 110 of the present invention is further provided with a through hole 113, which can be a countersunk hole so that when the back plate 110 and the ring component 150 are connected by a self-tapping screw, the head of the self-tapping screw can be located in the countersunk hole without being exposed from the back plate 110.

[0069] Preferably, the through holes 113 are provided in plurality along the periphery of the back plate 110. Figure 3 In the illustrated embodiment, the number of through holes 113 may be 12, and these through holes 113 may also be evenly spaced along the circumference of the back plate 110. Of course, considering that the size and shape of the back plate 110 may vary, the number of through holes 113 may also be other values, and the arrangement positions of the through holes 113 may also vary.

[0070] like Figure 2 As shown, in the present disclosure, the light-emitting component 120 is arranged on the back panel 110 and is used to emit visible light (the visible light can be white light); in a preferred embodiment, the light-emitting component 120 includes a plurality of LED light strips, and the plurality of LED light strips are arranged on the back panel 110, and these LED light strips are arranged approximately parallel to each other.

[0071] In the present disclosure, the number of the LED light strips can be set to six. Taking the back plate 110 in a vertical state as an example, these LED light strips can be arranged approximately vertically.

[0072] The LED light strip can include multiple LED light-emitting chips. The light emitted by the LED light-emitting chips is then directed to the panel 130 through a focusing lens, thereby enhancing the focus and uniformity of the optical fiber and improving the lighting effect. In a preferred embodiment, the LED light-emitting chips can be evenly spaced on the LED light strip to improve the uniformity of the light radiated by the light box 100.

[0073] The light box 100 of the present disclosure may further include a ring member 150, which can be fixedly connected to the back panel 110. Furthermore, the side portion 140 is connected to the back panel 110 via the ring member 150. The ring member 150 is made of a light-transmitting material. When the light box 100 of the present disclosure is mounted on a vertical wall, light transmitted through the ring member 150 can illuminate the wall near the light box 100, thereby creating a soft lighting atmosphere and enhancing the aesthetics of the light box.

[0074] In a specific embodiment, the ring component 150 can be made of translucent frosted ABS material or translucent frosted acrylic material.

[0075] Figure 4 Schematic diagram of the structure of a ring component according to one embodiment of the present disclosure.

[0076] like Figure 4 As shown, a receiving portion is formed on the ring member 150 of the present disclosure, and the edge of the back plate 110 is located in the receiving portion, thereby allowing the ring member 150 of the present disclosure to be disposed around the back plate 110. Specifically, the ring member 150 includes a base portion 151 and an extension portion 152 extending from the base portion 151, wherein the extension portion 152 is used to form at least a portion of the side wall of the receiving portion, and the extension portion 152 is disposed in contact with the inner surface of the back plate 110, and the back plate 110 is connected to the extension portion 152.

[0077] Thus, the base 151 of the ring member 150 of the present disclosure can form at least a portion of the rear surface of the light box 100 ; in other words, the rear surface of the back plate 110 and a portion of the surface of the base 151 can jointly form the rear surface of the light box 100 .

[0078] More specifically, the extension portion 152 of the present invention is provided with a through hole, the diameter of which is smaller than the diameter of the self-tapping screw. Thus, the self-tapping screw can pass through the through hole of the back plate and be screwed into the through hole of the extension portion 152, causing the through hole of the extension portion 152 to deform and form threaded teeth, thereby achieving a fixed connection between the back plate 110 and the ring component 150.

[0079] In one embodiment, an inserting portion 153 is formed on the base 151; for example, the inserting portion 153 is formed in an annular shape as a whole and extends from the base 151 in a direction away from the back plate 110. In other words, the inserting portion 153 of the present disclosure can be formed as an annular protrusion.

[0080] Figure 5 It is a schematic structural diagram of the side portion according to an embodiment of the present disclosure.

[0081] like Figure 5 As shown, the side portion 140 of the present disclosure is generally formed into a cylindrical structure. Specifically, the side portion 140 includes a first end and a second end in the axial direction. In one embodiment, the first end of the side portion 140 can be directly connected to the back plate 110; in another embodiment, the first end of the side portion 140 can be indirectly connected to the back plate 110 via a ring member 150. In other words, in a preferred embodiment, the first end of the side portion 140 can be connected to the ring member 150.

[0082] Specifically, if Figure 5 As shown, an insertion groove 141 is formed at the first end of the side portion 140 . The insertion groove 141 is formed as an annular groove. The side portion 140 is connected to the ring component 150 by the engagement of the insertion portion 153 with the insertion groove 141 .

[0083] In a preferred embodiment, the contact portion between the side portion 140 and the ring component 150 may be coated with glue so that the side portion 140 can be firmly connected to the ring component 150 .

[0084] Of course, the insertion groove may also be formed on the base portion 151 of the ring member 150 , and in this case, an insertion portion may be formed on the side portion 140 .

[0085] The second end of the side portion 140 is connected to the panel 130, and the outer circumference of the side portion 140 and the outer circumference of the panel 130 are projected on the same plane on the back plate 110. In other words, the light box 100 of the present disclosure is substantially formed in a columnar shape.

[0086] In a specific embodiment, the side portion 140 is integrally injection-molded from a milky white ABS material and forms at least a portion of the housing of the light box 100 of the present disclosure. Furthermore, due to the light-blocking properties of the side portion 140, the propagation direction of light can be effectively controlled, thereby improving the display effect of the light box 100.

[0087] like Figure 2 As shown, the side portion 140 and the panel 130 may adopt an overlapping structure and be fixedly connected by gluing.

[0088] Specifically, if Figure 2As shown, the panel 130 includes an inner surface and a first step surface 131, and a step portion is formed by the first step surface 131, wherein the inner surface of the panel 130 and the first step surface 131 are located in different vertical planes. More preferably, the inner surface of the panel 130 is located closer to the back panel 110 and closer to the interior of the light box 100.

[0089] On the other hand, the second end of the side portion 140 has an end surface 142; the second end of the side portion 140 also includes a second stepped surface 143. Accordingly, the end surface 142 and the second stepped surface 143 are located in different vertical planes. More preferably, the second stepped surface 143 is located closer to the back panel 110 and closer to the interior of the light box 100.

[0090] When the panel 130 is mounted on the side portion 140, the inner surface of the panel 130 contacts and mates with the second step surface 143 of the side portion 140, and the end surface 142 of the side portion 140 contacts and mates with the first step surface 131 of the panel 130. More preferably, glue may be applied at the contact point between the panel 130 and the side portion 140, so that the panel 130 and the side portion 140 can be firmly fixed together.

[0091] In the present disclosure, there is a gap between the back panel 110 and the panel 130; wherein, the light-emitting component 120 is located between the back panel 110 and the panel 130, and there is a preset distance between the light-emitting component 120 and the back panel 110. Thus, the light generated by the light-emitting component 120 can be more evenly irradiated to the panel 130 without generating a relatively bright light spot on the panel 130, thereby improving the lighting effect of the light box 100.

[0092] In a specific embodiment, the panel 130 is made of a milky white acrylic material, so that the LOGO in the film layer 160 can be displayed more clearly when the light box 100 of the present disclosure is in use.

[0093] Figure 6 Schematic diagram of the structure of a film layer according to one embodiment of the present disclosure.

[0094] like Figure 6 As shown, in a preferred embodiment, a film layer 160 may be provided on the panel 130, and information such as text and / or patterns may be displayed through the film layer 160. The text and / or pattern information may be a company logo or trademark (LOGO).

[0095] For example, the film layer 160 can be prepared using a translucent film of different colors, and a hollow area 161 with text and / or patterns can be formed on the film layer 160, so that the hollow area 161 appears white (that is, the LED chip can emit white light); accordingly, the non-hollowed-out part of the film layer 160 will appear as the color of the translucent film itself, so that the logo or trademark can be displayed more clearly and brightly, thereby enhancing the brand recognition.

[0096] by Figure 6 For example, the letters “d” and “y” can be displayed on the film layer 160 . Accordingly, the letters “d” and “y” are formed by removing part of the light-transmitting film on the film layer 160 , that is, by hollowing out.

[0097] The light box 100 formed by the above structure has a storage space formed between the back plate 110, the side portions 140, and the front panel 130, which is the interior of the light box 100. Moreover, the outer peripheral surface of the side portion 140 and the outer peripheral surface of the front panel 130 are projected on the back plate 110 in the same manner, that is, the light box 100 of the present disclosure is generally formed into a cylindrical structure, thereby making it convenient for users to hold and install the light box.

[0098] At least part of the surface of the ring member 150 forms at least part of the wall of the receiving space. In other words, the light emitted by the LED chip of the present disclosure can directly irradiate or emit to the ring member 150 and irradiate to a wall or other location through the ring member 150.

[0099] In the present disclosure, the light box 100 further includes a transformer (e.g., a long, ultra-thin transformer) that can be connected to the mains electricity supply and provide power to the light-emitting component 120. The transformer is disposed within the light box 100. Therefore, during installation, the light box 100 of the present disclosure can be installed by simply connecting the cable connected to the transformer to the mains electricity supply. This facilitates installation of the light box 100 and resolves the existing problem of an external transformer, which can be inconvenient to install and often prevents installation.

[0100] Overall, the light box 100 formed by the above-described structure significantly improves its durability and stability. Furthermore, the provision of opaque side portions effectively controls the direction of light propagation, reducing light pollution. This, in turn, reduces the power of the light-emitting components, saving energy. Furthermore, the light box 100 of the present disclosure has an aesthetically pleasing overall appearance, blending seamlessly with its surroundings and enhancing its brand image.
